Easy to flip the pages in a book when fingertip is wet
Burning of hydrogen gas in oxygen gas
Lowe the melting point of ethanol
Salt is able to dissolve in water
Why do hair sticks together when it is wet?
Because there are hydrogen bonds between water molecules with the protein molecules in the air
Because there are covalent bonds between water molecules and protein molecules
Because the water adhesive force is greater than the repulsion force
Because the van der Waals forces between molecules are formed
